This letter presents a photocurrent readout for bioluminescence detection. The design incorporates an asynchronous architecture employing a proposed capacitive feedback transimpedance amplifier (C-TIA) with a self-timed reset network and an all-digital reconfigurable time-domain quantization scheme. It eliminates the need for a periodic reset signal required in conventional C-TIAs and offers a wide dynamic range (DR) of 124 dB, a nonlinearity of 1.7%, and a 1-pArms input-referred noise while drawing only $210~mu $
